I have discovered a new word to be banned from the English language. It is ‘so’, especially when people are asked questions, thus:

Q: What job do you do, Fred?

A: So, I used to be a doctor…

Q: Emma, what are your hobbies?

A: So, I used to have a cat that loved sardines…

It adds nothing to anything. All people who start sentences with this word should disappear…
